KODAK Color Science
Behind every picture you take is over a century of imaging science dedicated to giving you quality pictures. KODAK color science and imaging technologies are used by professional photographers and professional color labs, and are even incorporated in imaging systems that have traveled to outer space.

KODAK Color Science Replicates the Human Color Experience
Human perception of color is a science in itself – one in which Kodak has excelled for more than a century. Human vision is the result of your eyes and brain working together. The rods and cones in the retina of the human eye convert light intensity and color respectively into electrical impulses that are sent to the brain where they are converted into information about what we are seeing. Likewise, the sensor in a digital camera converts light intensity and color information from the scene into a picture file that represents the original scene. Kodak scientists developed the color filter pattern that allows most of today’s image sensors to “see” in color. This color filter array allows a single image sensor to capture the red, green, and blue components of an image in one “click.”
To produce a high quality color image, the sophisticated algorithms of KODAK color science process the raw image signal in KODAK EASYSHARE digital cameras. KODAK color science controls the essential elements of image quality by determining proper exposure, auto white balance, and accurate color reproduction.

Proper Exposure
Exposure determines picture brightness. The proper exposure delivers optimal image quality, detail, and color reproduction. Unlike other cameras that rely solely on brightness to calculate optimal exposure, Kodak’s image processing algorithms take information from nearly 100 adjacent scene areas and analyze the areas for color, subject orientation, and brightness to determine the proper exposure. The result is outstanding exposure, shot after shot, even in challenging situations such as backlit scenes or high-contrast situations.

Auto White Balance
The human eye has the ability to perceive white as white, even under yellowish tungsten light, such as a reading lamp, or greenish fluorescent lighting. A digital camera’s sensor records the scene as it is without compensating for the source of light, making indoor-lit scenes appear off-color to the human eye. Auto white balance applies a sophisticated set of algorithms to detect the characteristics of the light source and to correct for any shift in color that’s needed. Kodak’s auto white balance is among the best in the industry and is another element of KODAK color science.

KODAK Color Science Image Processing
Each time you press the shutter on a KODAK EASYSHARE digital camera, KODAK color science is applied to produce exceptional quality images shot after shot. What’s more – in cameras that use the KODAK color science chip, the image processing is accelerated for higher performance. A digital signal processor, smaller than the size of a dime, enables a multitude of performance enhancement features that work together with proprietary imaging processing algorithms for outstanding results. While the function of the chip is customized and optimized for each camera model, the results are consistent– rich, vibrant, true-to-life colors and accurate flesh tones.
